In this remarkable new perspective on the human love of animals, anthropologist Pat Shipman reveals that the domestication of animals has not only changed them, it has had a profound developmental impact on us as well. Indeed, as Shipman demonstrates, our propensity to domesticate and care for other animals is a profoundly human characteristic, offering definite adaptive and cultural advantages, and is one of our species' greatest strengths. Touring the milestones of 2.6 million years in human civilization, from agriculture to art and even language, Shipman describes how we reached each stage through our unique relationship with other animals.

"Pat Shipman gathers together the results of many archaeological studies, and she clearly shows how animals were intimately involved in the development of early humans. Both animal lovers and readers who are interested in human psychology will not be able to put this fascinating book down."—Temple Grandin

"Shipman takes us on a journey through human evolution as it has never been told before. She demonstrates that humanity emerged not only through tool use and language, but because of our associations with animals. Shipman's triumph is her demonstration that the modern human condition was borne of our personal connections with animals—from horses as transportation, to cows and sheep as food, to dogs as vigilant companions. Our achievements on two legs were made possible by our many relatives on four."—Nina G. Jablonski
